However, a ladder may be installed diagonally between the equipment installation surface and equipment such as an elevated water tank. In other words, a step of appropriate height was placed on the equipment installation surface. However, if the ladder is installed at an angle, the worker will move it up and down. There is a problem that the ladder easily shifts and the posture of the worker becomes unstable. Even when the step is placed on the equipment installation surface, the operator can move up and down to the end of the step. However, there is a drawback that the posture of the worker becomes unstable.
